Stopped working with "Addon needs to update some data from 'translate.google.com', please try again after few seconds..." and opening Google Translator page.

Fix for Google Translator addon (broken API)
The addon stopped working because Google discontinued the google.com/async/translate endpoint it relied on, as well as the TKK token system used as fallback.
Solution: Replace the _getEmbedTranslation function in lib/common.js with a call to the stable translate.googleapis.com/translate_a/single?client=gtx API, which requires no token and returns clean JSON.
The new endpoint URL pattern:
h t t p s://translate.googleapis.com/translate_a/single?client=gtx&sl={from}&tl={to}&dt=t&dt=bd&dt=rm&dj=1&q={word}
The response is parsed via data.sentences[].trans to extract the translation, and data.src for the detected source language.
The returned object structure is kept identical to the original so the rest of the addon works without any other changes.
How to apply: Open the .xpi file with 7-Zip, navigate to lib/common.js, and replace it with the patched version.

The best UI to translate unfamiliar word or phrase.

Permission "Access your data for all websites" is not needed when working with the current page only.

Finally an extension that can automatically translate the text and doesn't require to click something! I also love the ability to change the colors and overall the plethora of options!

5/5 for me!!!

All this is is a front end to the google translate page. It saves a little time as it takes you write to the text boxes and you can translate an entire page. Google is getting good at translations, fewer and fewer nonsensicle results. But of course they are spying on you and profiling you when you use it, because that is the evil nature of google. But it works better than imtranslator which puts malware on your machine to open their webpage w/out your permission.

not work now
